Zinc PCA (Zinc Pyrrolidone Carboxylate) is a zinc salt compound formed by the combination of zinc ions and pyrrolidone carboxylic acid (PCA). PCA is a key component of the skin's natural moisturizing factor (NMF), while zinc is known for its oil-control, antibacterial, and reparative properties.
Zinc PCA is a white to pale yellow crystalline powder, the zinc salt of L-Pyrrolidone 5-carboxylic acid (PCA) which is a natural moisturizing factor (NMF) of amino acid type. Easily soluble in water, it can be used in water-based applications providing exceptional dermal hydration and boosting the moisture-binding ability of the skin.
Benefits:
-
Oil Control: Zinc PCA helps regulate sebum production, reducing shine and making it particularly suitable for oily and combination skin.
-
Antibacterial: It has antibacterial and anti-inflammatory properties, helping to reduce the formation of acne and pimples.
-
Moisturizing: As a component of the natural moisturizing factor, Zinc PCA helps lock in moisture, keeping the skin hydrated.
